ABB Battery Module AM811F
Features
Provides battery backup
Enables redundant battery energy backup on the AC 800F
Description
The battery module provides for retention of the AC 800F RAM
data when the AC 800F is off or has no Ethernet module.
The battery module is used when the AC 800F is used as a
stand-alone device, i.e. when it has no Ethernet connection, or
when the only existing Ethernet module is to be replaced with out the AC 800F loosing its configuration data.
LED Displays
State
Off No supply power, module is isolated
Green Power supply on, module identified and
ready to operate as configured.
Orange Power supply on, module identified and ei ther:
— normal transitory state after module
startup
— configuration mode of Boot Loader
Red Module power supply is on and either:
— module not yet identified (normal for
short time, during module startup)
— error occurred during module test
Battery (PM803F)
Off AC 800F is active, AM 811F not active
=>buffering from power supply module
AC 800F is off (no watchdog of the batter ies voltage) =>buffering from battery.
Orange During battery recovery or start-up phase
Red Warning: battery low, no battery inserted,
insufficient electrical contact etc.
Green battery inserted and data protection pro vided.
Battery (PM802F)
Off Sufficient buffer battery voltage
Orange Buffer battery not found or low (insufficient
voltage).
